Immunostaining for the p53 protein was found in 23\/102 (23 per cent) cases of the Barrett's oesophagus biopsies and in 12\/23 (52 per cent) cases of Barrett's oesophagus adjacent to adenocarcinoma. Significant correlations were found between the grade of dysplasia and p53 immunoreactivity in both Barrett's biopsies without adenocarcinoma (<jats:italic>P<\/jats:italic>&lt;0.001) and Barrett's oesophagus adjacent to adenocarcinoma (<jats:italic>P<\/jats:italic>&lt;0.05). In the adenocarcinomas, intense nuclear immunohistochemical staining for p53 was diffusely or focally present in 20\/24 (83 per cent) of the specimens. In Barrett's oesophagus, p53 is a progression marker with high expression in high\u2010grade dysplasia (89 per cent) and adenocarcinoma (83 per cent).<\/jats:p>","DOI":"10.1002\/path.1711750204","type":"journal-article","created":{"date-parts":[[2005,6,22]],"date-time":"2005-06-22T13:12:34Z","timestamp":1119445954000},"page":"175-180","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":56,"title":["Accumulation of p53 protein in normal, dysplastic, and neoplastic Barrett's oesophagus"],"prefix":"10.1002","volume":"175","author":[{"given":"Kausilia K.","family":"Krishnadath","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hugo W.","family":"Tilanus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"van Blankenstein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fre T.","family":"Bosman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andries H.","family":"Mulder","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,6,15]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.18003815005"},{"key":"e_1_2_1_3_2","first-page":"573","article-title":"Barrett's oesophagus","volume":"8","author":"Spechler SJ","year":"1992","journal-title":"Gastroenterology"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0016-5085(84)90090-8"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/gut.30.1.14"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0016-5085(93)90017-7"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2036.1993.tb00107.x"},{"key":"e_1_2_1_8_2","first-page":"145","article-title":"Widespread p53 overexpression in human malignant tumors.
